“…The organic fraction is then biodegraded under the aerobic condition until all the oxygen has depleted in the subsurface. Then, it will pave the way for the anaerobic biodegradation of remnant organics to transpire while spewing methane gas into atmosphere which is 25 times more powerful than CO2 to cause global warming (Amritha and Anilkumar, 2016). In fact, landfilling has crowded out as the third largest source of methane emissions globally (Amritha and Anilkumar, 2016;Zhao et al, 2019).…”

The increase of annual organic wastes generated worldwide has become a major problem for many countries since the mismanagement could bring about negative effects on the environment besides, being costly for an innocuous disposal. Recently, insect larvae have been investigated to valorize organic wastes. This entomoremediation approach is rising from the ability of the insect larvae to convert organic wastes into its biomass via assimilation process as catapulted by the natural demand to complete its lifecycle. Among the insect species, black soldier fly or Hermetia illucens is widely researched since the larvae can grow in various environments while being saprophagous in nature. Even though black soldier fly larvae (BSFL) can ingest various decay materials, some organic wastes such as sewage sludge or lignocellulosic wastes such as waste coconut endosperm are destitute of decent nutrients that could retard the BSFL growth. Hence, blending with nutrient-rich low-cost substrates such as palm kernel expeller, soybean curd residue, etc. is employed to fortify the nutritional contents of larval feeding substrates prior to administering to the BSFL.Alternatively, microbial fermentation can be adopted to breakdown the lignocellulosic wastes, exuding essential nutrients for growing BSFL. Upon reaching maturity, the BSFL can be harvested to serve as the protein and lipid feedstock. The larval protein can be made into insect meal for farmed animals, whilst the lipid source could be extracted and transesterified into larval biodiesel to cushion the global energy demands. Henceforth, this review presents the influence of various organic wastes introduced to feed BSFL, targeting to reduce wastes and producing biochemicals from mature larvae through entomoremediation. Modification of recalcitrant organic wastes via fermentation processes is also unveiled to ameliorate the BSFL growth. Lastly, the sustainable applications of harvested BSFL biomass are as well covered together with the immediate shortcomings that entail further researches.

“…Improper handling can cause environmental pollution and disease spread, and there are few resource-based applications of these organic waste, which has become a major obstacle to carbon emission reduction in the new century. Therefore, if these large amounts of organic waste are disposed of arbitrarily without taking effective measures, it will not only affect the appearance of the city but also cause different degrees of environmental pollution [2,3]. At present, China has issued a series of policies intended to use food waste compost and garden waste for soil quality improvement [4].…”

It is important to understand the dynamics of soil carbon to study the effects of waste amendment inputs on soil organic carbon decomposition. The aim of this study was to evaluate the effect of waste amendment carbon input on the soil organic carbon (SOC) content, soil particulate organic carbon (POC) content and soil organic carbon mineralization rate dynamics. A 60-day experiment was carried out in the laboratory. The following treatments were compared: (1) CK: soil without amendments; (2) FW1: soil with food waste compost (soil/food waste compost = 100:1); (3) FW2: soil with food waste compost (soil/food waste compost = 100:2); (4) GW1: soil with garden waste compost (soil/garden waste compost = 100:0.84); (5) GW2: soil with garden waste compost (soil/garden waste compost = 100:1.67); (6) FGW1: soil amendments mixture (soil/food waste compost/garden waste compost = 100:0.5:0.42); (7) FGW2: soil amendments mixture (soil/food waste compost/garden waste compost = 100:1:0.84); the inputs of amendment carbon to FW1, GW1 and FGW1 were 2.92 g kg−1, the inputs of amendment carbon to FW2, GW2 and FGW2 were 5.84 g kg−1. The results showed that the addition of waste amendments increased the amount of cumulative mineralization from 95% to 262% and accelerated the rate of soil mineralization. After adding organic materials, the change in the soil organic carbon mineralization rate could be divided into two stages: the fast stage and the slow stage. The dividing point of the two stages was approximately 10 days. When equal amounts of waste amendment carbon were input to the soil, there was no significant difference in SOC between food waste and garden waste. However, SOC increased with the amount of amendment addition. However, for POC, there was no significant difference between the different amounts of carbon input to the garden waste compost treatments. SOC and POC were significantly correlated with the cumulative emissions of CO2.

In this study, the concept of Microbial Fuel Cells (MFCs) is applied in the biological cathodic protection (CP) system. MFCs are a promising technology for electricity production from a variety of materials. Impressed current cathodic protection (ICCP) was the tradition method used in corrosion control method. Biological CP uses the microbiological presence in wastewater to generate the electrons. The focus of this study is on the effect of organic waste towards the biological CP system. The selected organic wastes are orange peel and pineapple peel. The presence of starch and sugar in the organic waste are promote the microbial growth and increase the performance of biological CP system. The method used to prepare the substrate was based on the previous studies and the CP system was a single chamber system. Current and power density was calculated from the experimental data of the specific weight of substrates and the results was discussed in this study. The weight of substrate are manipulated for each experiment. The statistical analysis was done on the voltage potential output for the selected optimum substrate's weight and the result was varies for each of organic waste used. The highest voltage potential output by the CP system was 920 mV (20 grams of orange peel) and 1046 mV (40 grams of pineapple peel).
